Please excuse reporting deficiencies, I'll endeavour to fix them as best I can once pointed out. + +In my spare time, I help out for the packaging effort in the [conda-forge](https://conda-forge.org/) ecosystem, which is mostly associated/attached to the python world, but - in contrast to the vanilla python tools - also deals with non-python dependencies, and in particular has strong enough abstractions to deal with ABI-issues and generally provides much better integration than the packages on PyPI. + +This strength of abstraction has also allowed conda-forge to publish artefacts for many more architectures than most projects are commonly able to provide precompiled binaries for. Due to the lack of (reliable) public CI for aarch64 & ppc64le, these packages are mostly cross-compiled from linux-x86. Where cross compilation is not possible, the packages are compiled in emulation through QEMU, coming through https://github.com/multiarch/qemu-user-static (this is the part of the infrastructure I don't fully understand myself...). The full infrastructure is somewhat involved, but should not be relevant (hopefully) to the issue at hand (see instructions below) - and even if that turns out to be the case, that would be a great information gain as well. + +In either case, the tests for the package (ideally comprising the entire upstream test suite) are then run in emulation. + +Two of the so-called "feedstocks" I co-maintain are for [numpy](https://github.com/conda-forge/numpy-feedstock) and [scipy](https://github.com/conda-forge/scipy-feedstock), and there have been persistent issues with running the test suite in emulation on PPC (interestingly, the same setup on a different architecture - aarch64 - has no problems).

But these days we've moved handling of semihosting out to an entirely different codepath, so we can fix this bug by simply removing this handling of EXCP_BKPT and instead making it deliver a SIGTRAP like EXCP_DEBUG (as we do already on aarch64). \ No newline at end of file diff --git a/results/classifier/deepseek-r1:32b/output/instruction/1874888 b/results/classifier/deepseek-r1:32b/output/instruction/1874888 new file mode 100644 index 000000000..8a9610f12 --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/instruction/1874888 @@ -0,0 +1,46 @@ + + + +certain programs make QEMU crash with "tcg fatal error" + +The following code snippet crashes qemu with + +.../tcg/tcg.c:3279: tcg fatal error +qemu-x86_64: /usr/local/google/home/kostik/qemu-5.0.0-rc4/accel/tcg/cpu-exec.c:701: int cpu_exec(CPUState *): Assertion `!have_mmap_lock()' failed. + +================ +int main() { + /* +00000000 <.data>: + 0: 2e 45 71 ff cs rex.RB jno 0x3 + 4: e9 00 00 f0 00 jmp 0xf00009 + 9: c4 42 7d 31 3e vpmovzxbd ymm15,QWORD PTR [r14] + e: c4 a3 7d 08 64 82 44 vroundps ymm4,YMMWORD PTR [rdx+r8*4+0x44],0x0 + 15: 00 + 16: 0f 1e 0a nop DWORD PTR [rdx] + 19: 43 0f ec 20 rex.XB paddsb mm4,QWORD PTR [r8] + 1d: 66 47 0f 3a 0c 3d 00 rex.RXB blendps xmm15,XMMWORD PTR [rip+0x8000],0x0 # 0x8028 + 24: 80 00 00 00 + 28: c4 e3 f9 df 5f 86 0d vaeskeygenassist xmm3,XMMWORD PTR [rdi-0x7a],0xd + 2f: c4 e2 55 92 74 fc 0a vgatherdps ymm6,DWORD PTR [rsp+ymm7*8+0xa],ymm5 + 36: c4 e2 f9 17 9a 01 00 vptest xmm3,XMMWORD PTR [rdx+0x1] + 3d: 00 00 +*/ + char buf[] = { + 0x2E, 0x45, 0x71, 0xFF, 0xE9, 0x00, 0x00, 0xF0, 0x00, 0xC4, 0x42, 0x7D, 0x31, 0x3E, 0xC4, 0xA3, 0x7D, 0x08, 0x64, 0x82, 0x44, 0x00, 0x0F, 0x1E, 0x0A, 0x43, 0x0F, 0xEC, 0x20, 0x66, 0x47, 0x0F, 0x3A, 0x0C, 0x3D, 0x00, 0x80, 0x00, 0x00, 0x00, 0xC4, 0xE3, 0xF9, 0xDF, 0x5F, 0x86, 0x0D, 0xC4, 0xE2, 0x55, 0x92, 0x74, 0xFC, 0x0A, 0xC4, 0xE2, 0xF9, 0x17, 0x9A, 0x01, 0x00, 0x00, 0x00 + }; + void (*f)(void) = (void (*) (void))buf; + f(); + return 0; +} +================ +Steps to reproduce: +1) clang -static repro.c -o repro +2) qemu-x86_64-static repro + +Tested with 4.2.0 and 5.0.0-rc4.

I investigated this for about 2 weeks, manually trying to trace the call stack, only to find that we seemingly crash in a bad shift instruction. Originally intended to be an shr_i64 generated to an RLDICL, we end up with an all ones(-1) c value, which gets thrown to the macro for generating the MB, and replaces the instruction with mostly ones. This new instruction, FFFFFFE0 is invalid on ppc64le, and crashes in a host SIGILL in codegen_buffer. I tried to see if the output of translate.c had this bad instruction, but all I got were two (shr eax, cl) instructions, and upon creating a test program with shr (eax, cl) in it, nothing happened. Then figuring that there was nothing actually wrong with the instruction in the first place, I turned my eye to the optimizer, and completely disabled constant folding for arithmetic instructions. This seemed to actually resolve the issue, and then I slowly enabled constant folding again on various instructions only to find that enabling not on the shifts, but on subtraction seemed to cause the bug to reappear. I am bewildered and frankly at this point I'm not sure I have a chance in hell of figuring out what causes it, so I'm throwing it here. \ No newline at end of file diff --git a/results/classifier/deepseek-r1:32b/output/instruction/1881450 b/results/classifier/deepseek-r1:32b/output/instruction/1881450 new file mode 100644 index 000000000..37d7e0e6e --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/instruction/1881450 @@ -0,0 +1,26 @@ + + + +Emulation of a math function fails for m68k Linux user mode + +Please check the attached math-example.c file. +When running the m68k executable under QEMU, it results in an "Illegal instruction" error. +Other targets don't produce this error. + +Steps to reproduce the bug: + +1.

The Asahi kernel has a 16K page-size, which is known to cause trouble for some programs. qemu-arm(-static) however works without any issues (the M1 cannot run 32-bit ARM code natively, only 64-bit). diff --git a/results/classifier/deepseek-r1:32b/output/runtime/1165383 b/results/classifier/deepseek-r1:32b/output/runtime/1165383 new file mode 100644 index 000000000..8571e394e --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/runtime/1165383 @@ -0,0 +1,6 @@ + + + +executable qemu-1.4.0/i386-linux-user/./qemu-i386 gives a segmentation fault + +executable qemu-1.4.0/i386-linux-user/./qemu-i386 gives a segmentation fault \ No newline at end of file diff --git a/results/classifier/deepseek-r1:32b/output/runtime/1172613 b/results/classifier/deepseek-r1:32b/output/runtime/1172613 new file mode 100644 index 000000000..fb4026413 --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/runtime/1172613 @@ -0,0 +1,66 @@ + + + +[qemu 1.4.1] inconsistent behavior on different architecture + +Running with qemu 1.4.1 and eglibc 2.17 on Debian Linux 7.0 for amd64 + +---------------- armhf ---------------- +$ arm-linux-gnueabihf-gcc hello.c +$ qemu-arm ./a.out +/lib/ld-linux-armhf.so.3: No such file or directory + +$ qemu-arm arm-linux-gnueabihf/lib/ld-2.17.so ./a.out +./a.out: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory + +$ qemu-arm arm-linux-gnueabihf/lib/ld-2.17.so --library-path arm-linux-gnueabihf/lib ./a.out +Hello, world ! + +---------------- powerpc64 ---------------- +$ powerpc64-linux-gcc hello.c + +$ qemu-ppc64 ./a.out +/lib64/ld64.so.1: No such file or directory + +[BAD BEHAVIOR !!!] +$ qemu-ppc64 powerpc64-linux/lib64/ld-2.17.so ./a.out +Invalid data memory access: 0x00000041988fd008 +NIP 000000400001cb2c LR 000000400001cc30 CTR 0000000000000000 XER 0000000000000000 +MSR 8000000002006000 HID0 0000000060000000 HF 8000000002006000 idx 0 +TB 00000000 00000000 +GPR00 0000000000000000 000000400083a220 0000004000041230 00000043309bd010 +GPR04 0000004000026f12 000000000000000b 000000000000002e 000000000000002e +GPR08 0000000000000030 000000008803fffc 00000041988fcff4 0000000000000037 +GPR12 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +GPR16 0000000000000000 000000400003a4d8 000000400083a6d0 000000400083a6d8 +GPR20 000000400003a898 000000000000000a 0000000000000000 00000043309bd010 +GPR24 0000004000037b60 00000000cfe8ced7 000000400003a430 0000000010000261 +GPR28 00000001980bfff4 0000000000000000 000000004401ffff 000000002200ffff +CR 22242224 [ E E E G E E E G ] RES ffffffffffffffff +FPR00 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR04 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR08 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR12 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR16 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR20 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR24 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPR28 0000000000000000 0000000000000000 0000000000000000 0000000000000000 +FPSCR 0000000000000000 +qemu: uncaught target signal 11 (Segmentation fault) - core dumped +Segmentation fault + +$ qemu-ppc64 powerpc64-linux/lib64/ld-2.17.so --library-path powerpc64-linux/lib64 ./a.out +Hello, world ! + +---------------- sparc64 ---------------- +$ sparc64-linux-gcc hello.c + +$ qemu-sparc64 ./a.out +/lib64/ld-linux.so.2: No such file or directory + +[BAD BEHAVIOR !!!] +$ qemu-sparc64 sparc64-linux/lib64/ld-2.17.so ./a.out +Segmentation fault + +$ qemu-sparc64 sparc64-linux/lib64/ld-2.17.so --library-path sparc64-linux/lib64 ./a.out +Hello, world ! \ No newline at end of file diff --git a/results/classifier/deepseek-r1:32b/output/runtime/1182490 b/results/classifier/deepseek-r1:32b/output/runtime/1182490 new file mode 100644 index 000000000..2fb9375e6 --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/runtime/1182490 @@ -0,0 +1,79 @@ + + + +[qemu-1.5] coroutine-win32.c broken on NULL pointer + +Program received signal SIGSEGV, Segmentation fault. +[Switching to Thread 4340.0x163c] +qemu_coroutine_switch (action=COROUTINE_TERMINATE, to_=0x0, from_=0x3ba1c80) + at /home/cauchy/vcs/git/qemu/coroutine-win32.c:47 +(gdb) bt +#0 qemu_coroutine_switch (action=COROUTINE_TERMINATE, to_=0x0, + from_=0x3ba1c80) at /home/cauchy/vcs/git/qemu/coroutine-win32.c:47 +#1 coroutine_trampoline (co_=0x3ba1c80) + at /home/cauchy/vcs/git/qemu/coroutine-win32.c:58 +#2 0x0000000077098fed in ??

This isn't just true on the +older builds, it's true with the 2.11 builds if I use the `-R` flag to +shrink the `guest_size` back down to 0xf7000000. That is with +linux-hardened 4.13.13 on x86-64. + +So then, it it falls back to crawling the entire address space; so it +tries base=0x00001000. With ASLR, that probably succeeds.

Once again, that has no relationship to the current +layout of the address space produced by the UPX de-compressor. +Steps to reproduce: +1. build qemu8-x86_64 from +``` +commit fcb237e64f9d026c03d635579c7b288d0008a6e5 (HEAD -> master, origin/master, origin/HEAD) +Merge: 2ff49e96ac c00aac6f14 +Date: Mon Jul 10 09:17:06 2023 +0100 +``` +2. run `build/qemu-x86_64 -strace upx-4.0.2-amd64_linux/upx --version` where the upx +is from https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-amd64_linux.tar.xz +3. output ends with +``` +372621 close(3) = 0 +372621 munmap(0x0000004000803000,3055) = 0 diff --git a/results/classifier/deepseek-r1:32b/output/runtime/1756519 b/results/classifier/deepseek-r1:32b/output/runtime/1756519 new file mode 100644 index 000000000..d6a31f730 --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/runtime/1756519 @@ -0,0 +1,49 @@ + + + +qemu linux-user crash in QOM path canonicalization during do_fork() call to cpu_create + +qemu-riscv64 version 2.11.50 (v2.11.0-2491-g2bb39a657a) crashes running gcc libgomp.c/sort-1.c testsuite test case with the following message: + +(process:11683): GLib-CRITICAL **: g_hash_table_iter_next: assertion 'ri->version == ri->hash_table->version' failed +** +ERROR:qom/object.c:1665:object_get_canonical_path_component: code should not be reached +qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x60139c16 + + +Backtrace obtained via gdb: + +#0 raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 +#1 0x0000000060139b21 in abort () at abort.c:79 +#2 0x0000000060100505 in g_assertion_message (domain=domain@entry=0x0, file=file@entry=0x60213ca1 "qom/object.c", line=line@entry=1665, + func=func@entry=0x60214420 <__func__.18106> "object_get_canonical_path_component", message=message@entry=0x7fffe8000cd0 "code should not be reached") + at gtestutils.c:2430 +#3 0x0000000060100586 in g_assertion_message_expr (domain=0x0, file=0x60213ca1 "qom/object.c", line=1665, + func=0x60214420 <__func__.18106> "object_get_canonical_path_component", expr=<optimized out>) at gtestutils.c:2453 +#4 0x0000000060098334 in object_get_canonical_path_component (obj=0x7fffe81340b0) at qom/object.c:1665 +#5 0x0000000060098366 in object_get_canonical_path (obj=0x7fffe81340b0) at qom/object.c:1675 +#6 0x000000006008e152 in device_set_realized (obj=0x7fffe81340b0, value=true, errp=0x7ffff762fe68) at hw/core/qdev.c:874 +#7 0x0000000060098bf4 in property_set_bool (obj=0x7fffe81340b0, v=0x7fffe80fd3c0, name=0x60213694 "realized", opaque=0x7fffe80fd140, errp=0x7ffff762fe68) + at qom/object.c:1926 +#8 0x0000000060096fee in object_property_set (obj=0x7fffe81340b0, v=0x7fffe80fd3c0, name=0x60213694 "realized", errp=0x7ffff762fe68) at qom/object.c:1122 +#9 0x0000000060099ebd in object_property_set_qobject (obj=0x7fffe81340b0, value=0x7fffe80fd310, name=0x60213694 "realized", errp=0x7ffff762fe68) + at qom/qom-qobject.c:27 +#10 0x0000000060097274 in object_property_set_bool (obj=0x7fffe81340b0, value=true, name=0x60213694 "realized", errp=0x7ffff762fe68) at qom/object.c:1191 +#11 0x0000000060092ec5 in cpu_create (typename=0x6250e1a0 "any-riscv-cpu") at qom/cpu.c:61 +#12 0x000000006009301a in cpu_generic_init (typename=0x601dd58f "riscv-cpu", cpu_model=0x601dd527 "any") at qom/cpu.c:98 +#13 0x000000006004cb61 in cpu_copy (env=0x7ffff008cd60) at /opt/qemu/linux-user/main.c:3881 +#14 0x000000006005b79a in do_fork (env=0x7ffff008cd60, flags=4001536, newsp=275531880704, parent_tidptr=275531882704, newtls=275531884288, + child_tidptr=275531882704) at /opt/qemu/linux-user/syscall.c:6348 +#15 0x0000000060063e56 in do_syscall (cpu_env=0x7ffff008cd60, num=220, arg1=4001536, arg2=275531880704, arg3=275531882704, arg4=275531884288, + arg5=275531882704, arg6=275531884288, arg7=0, arg8=0) at /opt/qemu/linux-user/syscall.c:10001 +#16 0x000000006004c89f in cpu_loop (env=0x7ffff008cd60) at /opt/qemu/linux-user/main.c:3600 +#17 0x000000006005b68f in clone_func (arg=0x7ffff7775050) at /opt/qemu/linux-user/syscall.c:6311 +#18 0x0000000060121797 in start_thread (arg=0x7ffff7632700) at pthread_create.c:463 +#19 0x000000006019b4fb in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 + + +Attached is a test case source code extracted from libgomp test suite. + +Note that it is a multi-threaded and requires 5 or more threads to fail.

FreeBSD `elf_aux_info` has `EINVAL` and `ENOENT` error codes but it's ignored here. On Linux, glibc sets `errno` to `ENOENT` to distinguish the two cases but only on glibc >= 2.19. Musl's `getauxval` has always had setting `errno` to `ENOENT`. + +Once we add a proper "`AT_EXECFD` doesn't exist" check this will no longer be a problem since (IIUC) `execfd` will eventually be closed after loading. How should we add "not found" support to `qemu_getauxval`? Is just simply relying on libc's `getauxval` setting `errno` okay? diff --git a/results/classifier/deepseek-r1:32b/output/runtime/2460 b/results/classifier/deepseek-r1:32b/output/runtime/2460 new file mode 100644 index 000000000..19cfd6dc9 --- /dev/null +++ b/results/classifier/deepseek-r1:32b/output/runtime/2460 @@ -0,0 +1,11 @@ + + + +Significant performance degradation of qemu-x86_64 starting from version 3 on aarch64 +Description of problem: +When I ran CoreMark with different qemu user-mode versions，guest x86-64-> host arm64, I found that the performance was highest with QEMU 2.x versions, and there was a significant performance degradation starting from QEMU version 3.

For a 64-bit value, shifting by more than 63 would result in zero because all bits are shifted out. But wait, the lower 5 bits can only be from 0 to 31 (since 2^5 = 32). So why is there an extra shift? + +Wait, looking at the code, a is `0x69C99AB9B9401024`. Taking the lower 5 bits of this value would be `a & 0b11111`, which is 4 in decimal because the last five bits are '000100' (binary) or 4. So the shift amount should be 4. + +Let me calculate what b shifted left by 4 should be. The value of b is `0xDB4D6868655C3585`. Shifting this left by 4 bits would result in `DB4D6868655C3585 << 4 = B4D6868655C35850` (since shifting each hex digit left by 4 is equivalent to multiplying by 16). + +But the output from QEMU is `55c3585000000000`, which looks like the correct shifted value but with an extra shift of 32 bits. Because if you take `B4D6868655C35850` and shift it left by 32, you get `55C3585000000000`. So why is this happening? + +Wait a minute, maybe the issue isn't with QEMU but how the variables are being handled. Let me check the C code again. + +The asm statement uses three operands: %0 for c (the result), %1 for b, and %2 for a. But in the RISC-V SLL instruction, the shift amount is only supposed to use the lower 5 bits of rs2. So in this case, a's value is `0x69C99AB9B9401024`, whose lower 5 bits are 4 (since 0x24 in hex is 36 in decimal, but wait, that can't be right because 0x24 is 36, which is more than 5 bits. Wait, no: the lower 5 bits of a would be the last five bits of the binary representation. + +Wait, 0x24 in hex is 00100100 in binary for an 8-bit value. But since we're dealing with a 64-bit register, the lower 5 bits are the least significant five bits of a's entire 64-bit value. So let me compute that. + +The variable a is `0x69C99AB9B9401024` as a 64-bit number. To find the lower 5 bits, I can compute a & 0b11111 (31). Let's calculate: + +a = 0x69C99AB9B9401024 +Let me extract the last 5 bits: +The hexadecimal digit '2' in 0x...024 is the last three bits. The full binary of 0x24 (last two hex digits) is 00100100, but for a 64-bit number, we need to look at all 5 bits. + +Wait, perhaps I made a mistake earlier. Let me compute a mod 32 because the lower 5 bits determine the shift amount. + +a = 0x69C99AB9B9401024 +To get a mod 32: The last five bits correspond to the value of a & 31. + +Let's calculate a in decimal and then mod by 32: + +But that's tedious. Alternatively, for any number, the lower 5 bits are determined by looking at the last two hex digits because each hex digit is four bits. So, 0x...024: The last two hex digits are '24'. Converting '24' to binary: 0010 0100. Now, take the lower five bits from this, which would be bits 0-4 (rightmost). Wait, no: for a 64-bit number, we need to consider all 64 bits and extract the last five. + +Alternatively, perhaps the issue is that when passing 'a' as the shift amount in the asm instruction, QEMU isn't correctly masking it to 5 bits. So if the third operand (rs2) has more than 5 bits set, the shift amount could be larger than intended, causing a bigger shift than expected. + +Wait, looking at the problem again: The correct_shift_res is calculated as b shifted left by (a & 0b11111), which is 4.

That suggests that somewhere, the shift amount is being treated as a larger number than intended, possibly because the masking isn't done correctly. + +So perhaps QEMU's SLL instruction is not properly applying the mask to the lower 5 bits of rs2 and instead uses the full value, leading to an incorrect shift amount. In this case, if rs2 is 'a', which has a value that when treated as a 64-bit integer is larger than 31 (since it's 0x...024), then using all bits could lead to a shift of more than 5 bits. + +Wait, no: the RISC-V SLL instruction only uses the lower 5 bits for the shift amount. So QEMU should be applying a mask of 0b11111 (31) to rs2 before shifting. If it's not doing that and instead using the full value of rs2, which is a large number like 0x69C99AB9B9401024, then the shift amount would be way larger than intended. + +In this case, if rs2 is used as is, its lower bits beyond 5 could cause a shift by more than 31. Let me see what 0x69C99AB9B9401024 mod 64 is (since shifting by 64 in 64-bit would result in zero). Wait, but that's not the case here because 0x24 is 36 in decimal. So 36 mod 64 is 36. Shifting a 64-bit number left by 36 bits would leave only the lower 64-36=28 bits set. + +Wait, but that doesn't align with the output seen. Alternatively, perhaps QEMU is treating the shift amount as signed or something else is wrong. + +Alternatively, maybe the issue is in how the operands are passed to the asm statement. Let me look at the C code again: + +asm volatile("sll %0, %1, %2" : "=r"(c) : "r"(b), "r"(a)); + +Here, 'a' is a uint64_t variable, and when used as an immediate in assembly, perhaps QEMU isn't correctly handling the shift amount. Or maybe the way the assembler interprets it is different. + +Wait, no, in RISC-V assembly, the SLL instruction uses rs2's lower 5 bits for the shift. So if 'a' is passed as a register, then the lower 5 bits should be used. But perhaps QEMU isn't correctly implementing this and instead using all bits of rs2 for the shift amount. + +So in the given example, rs2 is 0x69C99AB9B9401024, whose value mod 32 (since lower 5 bits) is 0x24 & 0b11111 = 4. So the correct shift should be by 4. + +But if QEMU isn't masking rs2 and instead uses the full value of a as the shift amount, which is 36 (from 0x24), then shifting b left by 36 would produce a different result. + +Wait, let's calculate that. Shifting 0xDB4D6868655C3585 left by 36 bits: + +In Python: + +b = 0xDB4D6868655C3585 +shift = 36 +result = (b << shift) & 0xFFFFFFFFFFFFFFFF + +But wait, that would be a very large shift. Let me compute it. + +Wait, but in reality, when shifting a 64-bit number left by 36 bits, the lower 28 bits would be zero, and the upper part would wrap around if beyond 64 bits. But let's see: + +The correct expected result is 0xB4D6868655C35850 after shifting by 4. + +But in QEMU, it's giving 0x55C3585000000000, which seems like the correct shift (by 4) followed by another shift of 32 bits. So 0xB4D6868655C35850 is 64 bits; shifting it left by another 32 would result in 0x55C3585000000000. + +So why would an extra shift happen? That suggests that the shift amount used was 36 (4 + 32), but that doesn't make sense. Alternatively, perhaps QEMU is using a different part of the register for the shift amount. + +Wait another angle: maybe the issue is with how the third operand is being treated as an immediate value instead of a register. In some assemblers, if you use an immediate without proper handling, it could cause unexpected behavior. + +But in this case, the asm statement uses 'r' constraints, meaning they're passed as registers. So rs2 should be the value from register a. + +Wait, perhaps QEMU is using the higher 5 bits instead of the lower 5? Or maybe there's an endianness issue. + +Alternatively, could it be that in some versions of RISC-V or QEMU, the shift amount isn't properly masked to 5 bits for SLL, leading to using more bits than intended? + +So putting this all together, the bug seems to be related to how the SLL instruction processes the shift amount.

This means only the least significant 5 bits of rs2 are considered for the shift amount. + +2. **Reproducing the Issue**: + - The provided code initializes two 64-bit variables `a` and `b`. + - It uses inline assembly to perform an SLL operation on `b` using the lower 5 bits of `a` as the shift amount. + - The expected result is a left shift by 4 bits (since `a & 0x1F = 4`), but QEMU's output shows an additional 32-bit shift. + +3. **Analyzing the Output**: + - Correct shift result: `(b << 4)` should be `0xB4D6868655C35850`. + - QEMU's incorrect result: `0x55C3585000000000`, which is the correct result shifted left by another 32 bits. + +4. **Identifying the Cause**: + - The extra shift suggests that instead of using only the lower 5 bits, QEMU uses a larger portion of `a`, possibly interpreting it as a signed or extended value beyond the intended 5 bits. + - This leads to an incorrect shift amount being applied, resulting in unexpected output. + +5. **Conclusion**: The issue lies within the SLL instruction's implementation in QEMU, where it does not correctly mask rs2 to use only the lower 5 bits for the shift amount, causing incorrect results. + +**Answer:** + +instruction \ No newline at end of file diff --git a/results/classifier/deepseek-r1:32b/reasoning/instruction/2419 b/results/classifier/deepseek-r1:32b/reasoning/instruction/2419 new file mode 100644 index 000000000..30273c302 --- /dev/null +++ b/results/classifier/deepseek-r1:32b/reasoning/instruction/2419 @@ -0,0 +1,15 @@ +<think> +Okay, so I need to classify this bug report into one of three categories: instruction, syscall, or runtime.

Because when you shift all ones right, each shift right would lose the least significant bit and fill with zero on the left. + +Wait no: For example: + +0b1111 shifted logically right by one → 0b0111 (since we drop the last bit and add a zero at the front). Similarly, shifting again gives 0b0011. So in 64 bits, all ones shifted right by two would be 0x3 followed by 62 zeros. + +Wait no: Wait, that's not correct because in reality, for example: + +In 8 bits, 0b11111111 (all ones) shifted logically right by one is 0b01111111. Then shifting again would be 0b00111111. + +So in 64 bits, the result of lsr x14, #2 would have the lower two bits as 1s and the rest as zeros? No, because each shift right by one adds a zero on the left. So after two shifts, it's 0x3 followed by 62 zeros. + +Wait but that can't be because shifting all ones (which is -1) logically right would produce a positive number. But in our case, x14 was set to -1 via csetm, which sets it to all ones. So when we shift it with lsr, the result should be 0x3 followed by 62 zeros. + +Then sxtb x0, w13: so w13 is lower 32 bits of x13. Since x13 after lsr is 0x3 followed by 62 zeros, then w13 (lower 32 bits) would be 0x00000003. + +sxtb takes the lower byte (8 bits) of w13: which is 0x03. Since it's a positive value (0x03 is less than 0x80), sign-extended to 64 bits, x0 becomes 0x0000000000000003. + +But according to the bug report, the result is 0x3fffffffffffffff, which is a large positive number. Hmm, that suggests that sxtb may be interpreting w13 differently. + +Wait wait: Let me think again about lsr x13, x14, x4. If x4 is 2, then it's shifting by two bits. But if the shift amount is larger than the register size, what happens? + +In AArch64, lsr with a variable shift (like using another register) shifts as per the lower byte of the shift value. So for example, if x4 is 65, then it would effectively be shifting by 1 (since 65 mod 64 is 1). But in our case, x4 is 2. + +Wait but wait: in the code, x4 is passed as c=2. So the shift amount is two. + +So lsr x13, x14, x4 would be shifting by 2 bits. + +But let's think about the value of x14 again. After csetm, x14 should be all ones (0xffffffffffffffff). Shifting that with lsr right by two gives 0x3 followed by 62 zeros? Or perhaps I'm making a mistake here. + +Wait no: Let me compute it as binary. All ones is 64 bits of 1s. Shifted logically right by two positions: + +Each bit moves to the right, and zero is added on the left. So after one shift, we get 0b111...111 (with a zero at the start). After another shift, we have 0b111...111 again? Wait no: wait, that can't be. + +Wait, perhaps I'm misunderstanding how shifting all ones works. Let's think differently: in two's complement, -1 is represented as all ones. Shifting it logically right by n bits would give a value with the lower n bits set to 1 and the rest filled with zeros. Wait no: that can't be correct because for example: + +0xFFFFFFFF (32-bit) shifted logical right by one gives 0x7FFFFFFF. + +Wait, maybe I'm mixing up signed and unsigned shifts. Let me try this step again. + +In AArch64, 'lsr' is a logical shift right, which treats the number as unsigned. So when you have x14 = 0xFFFFFFFFFFFFFFFF (which is -1 in two's complement), but treated as an unsigned value it's 0xFFFFFFFFFFFFFFFF. + +Shifting that logically right by 2 positions would result in 0x3 followed by 62 zeros? Or perhaps not, because shifting all ones by two would actually fill the lower bits with the higher bits of x14. Wait no: when you do a logical shift right, the bits are shifted to the right, and the vacated bits on the left are filled with zeros. + +So for example: + +0b1111 (all ones) shifted logically right by 2 → 0b0011. + +Similarly, in 64 bits, shifting all ones right by two would give us a value where the lower two bits are 1s and the rest are 0s. So x13 becomes 0x3 followed by 62 zeros? No, wait that can't be because it's 64 bits. + +Wait no: Let me think in terms of binary: + +Original x14 is 64 ones. + +After lsr x13, x14, #2 → shift right two positions. So the lower two bits would be lost (they are shifted out) and zeros are added on the left. + +So the result would be 0x3 followed by 62 zeros? No: because shifting all ones right by two would result in 0x0000000000000003. Because each shift to the right by one position drops a bit and adds a zero on the left. + +Wait, let me think step by step: + +- Start with x14: 64 bits all ones → binary '1' repeated 64 times. +- lsr x13, x14, #2: + - Shift right two positions. + - The first shift: rightmost bit (LSB) is lost; a zero is added to the left. So now, x13 is 0x7FFFFFFFFFFFFFFF (which is 63 ones followed by one zero). + - Second shift: again, the new LSB is shifted out (a zero this time), and another zero is added to the left. + - So after two shifts, we have 0x3 followed by 62 zeros? No, wait: + +Wait no. Let me think in terms of bits. + +Original x14: bit positions 63 down to 0 are all '1's. + +After shifting right by one: +- Bit position 63 becomes 0. +- Bits 62-0 become the original bits 63-1, respectively. +So after first shift: bit 63 is 0, others are 1s except for bit 0 which was shifted out. + +Wait no, shifting right by one would take each bit and move it to the next lower position. So: + +After lsr x14 #1: +bit 63 → 0, +bits 62-0 → original bits 63-1. + +So all bits except bit 63 are still '1's, and bit 63 is now 0. + +Wait that can't be right. Because when you do a logical shift right on an unsigned integer, the higher bits are filled with zeros. + +Ah, I see my confusion: in AArch64, the 'lsr' instruction shifts the value as if it's unsigned. So for x14 = 0xFFFFFFFFFFFFFFFF (all ones), which is -1 in signed but 2^64-1 in unsigned. + +Shifting that right by two would result in: + +(2^64 -1) / (2^2) → floor division, which would give us 0x3 followed by a lot of zeros? + +Wait, no. Wait, let's compute it numerically: + +The value is 0xFFFFFFFFFFFFFFFF (in hex), which is 2^64 - 1. + +Shifting that right by two bits: (2^64 -1) >> 2 = ? + +Well, in hexadecimal terms, each 'F' represents four bits. So shifting right by two positions would drop the last two bits and fill with zeros on the left. + +So 0xFFFFFFFFFFFFFFFF shifted right by two is 0x3 followed by a lot of Fs? + +Wait no: because if you have all ones and shift right by two, the higher bits are filled with zeros, so: + +In binary, shifting right by two would give us: + +Original: 111...111 (64 bits) +Shifted by two: 00 followed by 111...111, but only for 62 bits. + +Wait no, that's not correct. Because when you shift right by two positions, each bit moves to the next lower position twice. + +So after shifting, the value would be: + +Original (binary): + +bit63 ... bit0: all 1s + +After shifting right by two: + +bit63 and bit62 are set to 0. +bits61 down to 0 take the original bits63 down to 2. + +But since original bits were all 1s, after shift: + +bits63-62: 0 +bits61-0: 1 + +So in hex, that would be 0x0000000000000003 followed by zeros? No, wait. + +Wait no. Let me convert the shifted binary to hex: + +After shifting right two positions, we have: + +bits63-62: 0 +bits61-0: all ones except the last two bits (which were shifted out). + +So in terms of bytes: + +The first byte is now 0x00 (since the higher 8 bits are zeros). +Then follows bytes that are all 0xFF, but with the last two bits cleared? + +Wait no. Let's think in terms of shifting each bit. + +Wait perhaps a better approach: let me compute what happens when I shift 0xFFFFFFFFFFFFFFFF right by two positions using an unsigned right shift (which is what 'lsr' does). + +So: + +0xFFFFFFFFFFFFFFFF is equal to 2^64 -1. + +Shifting it right by two gives (2^64 -1) / (2^2) = (2^64 -1)/4. + +Which is 0x3 followed by 62 'F's? No, that can't be because shifting right in binary reduces the value, not increases. + +Wait no: Wait, no. Shifting right divides the number by two for each shift. So (2^64 -1) / 4 = 2^62 - (1/4), but since we're dealing with integers, it's floor division. + +So (2^64 -1) /4 = 0x3 followed by six 'F's and then some? + +Wait I'm getting confused. Let me calculate in hex: + +Shifting 0xFFFFFFFFFFFFFFFF right by two positions: + +Each shift to the right by one position is equivalent to dividing by two, but with integer division. + +So shifting right by one: 0x7FFFFFF... (since you lose the last bit). + +But for an all-ones number, shifting right as unsigned would fill with zeros on the left. So after shifting by two: + +The value becomes 0x3 followed by six 'F's and then more? + +Wait no, perhaps I'm overcomplicating it. + +Let me consider a smaller example: let's say we have a 8-bit number of all ones (0xFF). Shifting right by two positions as unsigned would result in 0x3F. Because: + +Original: 11111111 +After one shift: 01111111 +After another shift: 00111111, which is 0x3F. + +So for 8 bits, shifting right by two gives 0x3F. + +Similarly, in 64 bits, shifting all ones (0xFFFFFFFFFFFFFFFF) right by two positions would give us 0x3 followed by seven 'F's and then the rest? + +Wait no: wait, let me think. In an 8-bit number: + +After two shifts, we have 0x3F. + +In a 64-bit number, shifting all ones (0xFFFFFFFFFFFFFFFF) right by two positions would give us 0x3 followed by seven 'FF's and then the lower bits? Or is it 0x3 followed by more zeros? + +Wait no: Wait in an n-bit system, shifting all ones right by k positions gives a value where the higher k bits are zero, and the remaining (n -k) bits are one. + +So for 64 bits: + +Shifting two positions → first two bits are zero, next 62 bits are one. + +Which is 0x000000000000003F followed by ... no, wait in binary that would be 62 ones after the leading two zeros. So in hex, that's: + +Each four-bit nibble is a hexadecimal digit. So for 64 bits, if we have two leading zeros and 62 ones: + +The first nibble (bits 63-60) is 0x0, +the second nibble (59-56): 0x3, +and the rest would be 0xF each. + +Wait no: Let's count the bits. If we have two leading zeros, then in hex: + +The first byte (8 bits) would be 0x00 (since bits 63-56 are zero). + +Then the next six bytes (48 bits): each is 0xFF because those bits are ones. + +Wait no: Wait 62 bits after the two leading zeros. Let's calculate how that breaks down into hex digits: + +62 bits /4 = 15.5, which doesn't make sense. So perhaps it's better to think in terms of the entire 64-bit value. + +The result is 0x3 followed by six 'F's and then a half-byte? + +Wait I'm getting stuck here. Perhaps I should calculate the exact value after shifting. + +Original x14: 0xFFFFFFFFFFFFFFFF + +Shifting right two positions as unsigned: + +In binary, that would be: + +0b 1111 1111 ... (64 times) → shifted right by two gives: + +0b 00 followed by 62 ones. + +So in hex: + +Each byte is represented by two hex digits. Let's break down the 64 bits into eight bytes, each four bits. + +After shifting, the first two bits are zero, then 62 ones. + +In terms of bytes: + +The first byte (bits 63-56) would be 0b00 followed by six ones? No: because after two shifts, it's 0x00 in the first nibble and 0x3F in the next nibble? + +Wait perhaps a better way is to note that shifting right as unsigned in AArch64 for an all-ones number will result in a number where the lower bits are set. So after two shifts, it's 0x3 followed by 15 'Fs' (since each shift reduces the leading zeros and sets the trailing ones). + +Wait but I'm not getting anywhere with this. + +Alternatively, perhaps it's better to note that shifting right as unsigned for an all-ones number will result in a value where the higher bits are zero and lower bits are one up to 64 - k bits. So after two shifts, we have: + +0x3 followed by 15 'F's? Or is it something else. + +Wait perhaps I should just compute what (0xFFFFFFFFFFFFFFFF >> 2) is in hex. + +In Python, shifting right as unsigned would be done with bit_length and using the formula x >> n | ((x << (bit_length - n)) ) ? + +But let me do a quick calculation: + +(0xFFFFFFFFFFFFFFFF) is equal to (1<<64) -1. + +Shifting it right by two positions gives: + +((1<<64)-1) // 4 = (2^64 -1)/4. + +Which is 2^62 - 1/4, but since we're dealing with integers, it's floor division. + +So 2^62 -1 in integer terms. + +Wait no: Wait, ((1<<64)-1) //4 would be (2^64 -1)/4 = 2^62 - 0.25, which as an integer is 2^62 -1. + +Because 2^62 *4 = 2^64, so 2^64 -1 divided by four is 2^62 - (1/4). So in integer division, it's 2^62 -1. + +So the value after shifting is 0x3FFFFFF... something? + +Wait let me compute: + +2^62 is 0x4000000000000000. + +Subtracting one gives 0x3FFFFFFFFFFFFFFF. + +Yes, because: + +In hex, 0x4000000000000000 is 2^62. Subtract 1: 0x3FFFFFFFFFFFFFFF. + +So yes, shifting right by two positions of 0xFFFFFFFFFFFFFFFF as unsigned gives us 0x3 followed by fifteen 'F's and then the rest? Wait: + +Wait 2^62 -1 is equal to 0x3FFFFFFFFFFFFFFF. + +Because: + +2^64 / 4 = 2^62, so (2^64 -1)/4 = 2^62 - 1/4, which as integer division is 2^62 -1. + +And 2^62 in hex is 0x4000000000000000. + +Subtracting one gives us 0x3FFFFFFFFFFFFFFF. + +So after shifting right two positions, the value of x14 becomes 0x3FFFFFFFFFFFFFFF. + +Wait but wait: When you shift as unsigned, shifting all ones by two would give: + +bits63-2 are set to 1, bits1 and 0 are 0? + +No. Because when you do an unsigned right shift, the higher-order bits are filled with zeros. So shifting 0xFFFFFFFFFFFFFFFF (all ones) right by two positions gives us a number where the first two bits are zero, followed by all ones up to bit 2. + +Wait but in that case: + +After shifting two positions, we have: + +bit63 and bit62: 0, + +bits61 down to 0: 1s. + +So the value is 0x3 followed by six 'F's? No, let me count: + +From bit61 down to bit0: 62 bits. Each nibble (four bits) is a hex digit. So 62 bits /4 = 15.5, which suggests it can't be exactly represented. Wait no, perhaps I made a mistake. + +Wait in reality, 0x3FFFFFFFFFFFFFFF has only 62 bits set as ones. Let's see: + +Yes: the value is 0x3 followed by fifteen 'F's and ending with an F. Because 0x3 is one nibble (4 bits), then each 'F' is four bits, so 15 'F's would make 60 bits, plus the initial 0x3 makes total of 64 bits. + +Yes: + +- 0x3 is 4 bits, +- followed by fifteen 'F's: 15 *4 =60 bits, +Total: 64 bits. + +So 0x3FFFFFFFFFFFFFFF is correct after shifting. + +Therefore, the result of lsr x14 #2 would be 0x3FFFFFFFFFFFFFFF. + +Wait but this seems counterintuitive because shifting an all-ones number right as unsigned should set the higher-order bits to zero and keep lower ones as ones up to that point. + +Yes, so in this case, it's correct: 0x3 followed by fifteen 'F's is indeed 0x3FFFFFFFFFFFFFFF. + +So now, we have x13 = 0x3FFFFFFFFFFFFFFF. + +Next step: adding the value of x4 (which is 0) to it. + +Wait no. The instruction was 'add x13, x14, x4' which is add x14 and x4 into x13. + +But since x4 is zero, this would just copy x14 into x13. + +So after the shift right by two, we have x14 = 0x3FFFFFFFFFFFFFFF. Then adding x4 (zero) to it, x13 becomes the same value: 0x3FFFFFFFFFFFFFFF. + +But perhaps I'm overcomplicating; regardless, let's move on. + +Next instruction is 'add x29, x13, #0x7f'. + +So add 0x7F to x13 (which is 0x3FFFFFFFFFFFFFFF). + +What's the result? + +Adding 0x7F (which is 127 in decimal) to 0x3FFFFFFFFFFFFFFF. + +Let me calculate that: + +0x3FFFFFFFFFFFFFFF + 0x000000000000007F = ? + +Well, in hex: + +The last byte of x13 is 0xFF. Adding 0x7F to it would carry over: + +FF (255) + 7F (127) = 1FE (which is 254 in hex). So the lower byte becomes FE and a carryover of 1. + +But wait, adding 0xFF + 0x7F: + +In binary, 0xFF is 11111111, +0x7F is 01111111. + +Adding them: + +11111111 ++01111111 += (Carryover) 1 11111110 + +So the result in binary is 11111110 with a carryover of 1 to the next byte. + +But wait, let's compute this correctly: + +0xFF + 0x7F = 0xFF + 0x7F = 0x1FE (which is 254 in hex). So yes, lower byte becomes FE and carryover of 1. + +So adding 0x7F to x13 would result in: + +x29 = 0x3FFFFFFF...FE with a carryover affecting the previous bytes. + +Wait but since all the higher bytes are F except for the first two nibbles (which are 3), let's see how that addition propagates. + +But perhaps it's easier to compute this numerically. Let's see: + +0x3FFFFFFFFFFFFFFF is equal to (2^64 -1) //4, which we calculated earlier as 0x3FFFFFFFFFFFFFFF. + +Adding 0x7F gives us 0x3FFFF...FE. + +Yes, because adding 127 will cause the lower byte to roll over from FF to FE with a carryover. But since all the higher bytes are F's except for the first two nibbles, which are 3 followed by F's, adding 1 would turn each F into 0 and carry over, but in this case, we're adding only 7F (127), so it might not propagate beyond a few bytes. + +Wait no: Let me think. x13 is 0x3FFFFFFFFFFFFFFF. Adding 0x7F: + +The lower byte is FF + 7F = FE with carryover 1. +But the previous byte was FF, adding the carryover turns it to 00 with carryover 1. +This would propagate all the way through until we reach a non-FF byte. + +Wait but in x13, after the initial '3' (four bits), followed by fifteen 'F's and ending with an F? Wait no: earlier calculation said that x14 after shifting is 0x3FFFFFFFFFFFFFFF. + +So the bytes are: + +Bytes: + +[0x03][FF][FF]... [FF] + +Wait, no. Let me break down 0x3FFFFFFFFFFFFFFF into bytes. + +Each byte is two hex digits. + +Starting from the left: 0x3F FF FF FF FF FF FF FF. + +Wait that's 8 bytes (64 bits): + +0x3F, followed by seven 'FF's. + +So in terms of bytes: + +Byte 7: 0x3F +Bytes 6-0: 0xFF each + +So when we add 0x7F to this value, let's compute it step by step. + +The initial value is: + +byte 7: 0x3F (bits 111111) +bytes 6-0: 0xFF (each byte is 11111111) + +Adding 0x7F to this: + +We can represent the number as: + +0x3FFFFFFF FFFF FF FF FF FF FF FF + +When adding 0x00000000 0000 0000 0000 0000 0000 007F. + +The addition starts from the least significant byte: + +Byte 0: 0xFF + 0x7F = 0xFE (254) with carryover of 1. +But wait, FF is 255, adding 7F (127): 255 + 127 = 382. But in a byte, this overflows to FE (since 382 mod 256 = 382 - 256= 126, which is 0x7E). Wait wait, no: that's incorrect. + +Wait let me do it correctly: + +In binary: + +FF is 11111111 (255) +7F is 01111111 (127) + +Adding them gives: +11111111 ++01111111 += 1 01111110 + +So the sum is FE (254) with a carryover of 1. + +So byte 0 becomes FE, and we have to add the carryover to byte 1. + +But byte 1 was originally FF. Adding 1 gives: + +FF + 1 = 00 with carryover 1. + +So byte 1 becomes 00, and we carry over 1 to byte 2. + +Byte 2 was also FF: adding 1 gives 00 again, and carryover continues. + +This cascades all the way through bytes 2 up to byte 6, each of which was FF. So after adding 1, they all become 00 with a carryover propagating. + +Now, when we reach byte 7 (the highest byte in this case), which is 0x3F (00111111 in binary), we add the carryover: + +00111111 + 1 = 001111110, but since we're working with bytes, it would be 0x40 (binary 01000000) because we can't have a byte value of 0x3F + 1 as 0x40. + +Wait no: + +Actually, when adding the carryover to 0x3F (which is binary 00111111), adding 1 would make it 00111111 + 1 = 001111110? Wait that's not possible in a byte. Let me correct: + +Wait, when you add the carryover to byte7 (0x3F), which is 6 bits set: 00111111. + +Adding 1 gives 00111111 + 1 = 001111110? No, that's nine bits. Actually, when adding a carryover to byte7, we have: + +0x3F is 63 in decimal. Adding 1 (carryover) makes it 64, which is 0x40. + +But since each byte can only hold up to 0xFF, so yes, 0x3F +1 = 0x40 with no further carryover beyond that. + +So the resulting value after adding 0x7F is: + +Byte7: 0x40 +Bytes6-1: 0x00 (since each FF became 00 when carrying over) +Byte0: 0xFE + +So putting it all together, the new value of x29 is 0x40000000000000FE. + +Wait no: + +Because byte7 was originally 0x3F (which is six bits), adding carryover makes it 0x40. Then bytes6-1 were all FF, which after addition become 00 each due to the carryover propagation. Byte0 becomes FE. + +So yes: x29 = 0x40000000000000FE. + +Wait but let me count the number of bytes again: + +Total is 64 bits, so eight bytes. + +After adding: + +- byte7: 0x3F +1 (carryover) becomes 0x40. +- bytes6 to 1: each was FF and turned into 00 due to carryover propagation. +- byte0: FE. + +So x29 is 0x40 followed by seven bytes of 00, ending with FE. So in hex: + +0x40000000000000FE. + +Yes. + +Now, the next instruction is 'sub x31, xzr, x29'. + +Subtracting x29 from zero (since xzr is zero). Wait no: it's 'sub x31, xzr, x29', which means x31 = xzr - x29. + +Since xzr is zero, this becomes x31 = -x29. So the value is the negative of 0x40000000000000FE. + +In two's complement, subtracting a number from zero gives its two's complement. Alternatively, in assembly, 'sub x31, xzr, x29' would compute -x29. + +So x31 = 0xFFFFFFFFFFFFFE (the two's complement of x29). + +Wait but let me confirm: + +The value of x29 is 0x40000000000000FE. So the negative would be computed as: + +Two's complement: invert all bits and add one. + +But since it's a signed 64-bit integer, subtracting from zero gives us the two's complement representation of -x29. + +So x31 will hold the value -0x40000000000000FE. + +Now, moving on to 'add x5, x31, #0xff'. + +So adding 0xFF (255) to x31 (-0x40000000000000FE). + +Let's compute this: + +-0x40000000000000FE + 0xFF = ? + +But perhaps it's easier to work in two's complement. + +Alternatively, since x31 is -0x40000000000000FE, adding 0xFF would result in: + +-0x40000000000000FE + 0xFF = ? + +This can be written as -(0x40000000000000FE) + 0xFF. + +Alternatively, since we're dealing with two's complement: + +Adding a positive number to a negative number. + +The result will depend on the magnitude.

The user is using qemu-i386-static on a 64-bit machine and running into an issue where their malloc calls are returning pointers that seem off by 2 bytes each time they request memory. Let me break this down step by step. + +First, looking at the test program they provided, it's pretty straightforward. They're allocating four blocks of memory: two using `malloc(sizeof(uint32_t))` and two using `malloc(4)`. After that, they print out the pointers and check the size of uint32_t, which is 4 bytes as expected. + +The output shows the pointers increasing by 0x10 each time. Wait, no—looking at the numbers: pa is 0x400051a0, pb is 0x400051b0, pc is 0x400051c0, and pd is 0x400051d0. So each allocation increases by 0x10 (which is 16 in decimal), not 2 bytes as the user mentioned. Hmm, maybe I misread that part. + +Wait, no—the user said they applied for 4 bytes but the pointer increased by 2 bytes. That's confusing because from their output, each allocation increases by 16 bytes. Maybe there was a typo or misunderstanding in how they presented the issue. + +But assuming the actual problem is that the pointers are increasing by 2 bytes instead of 4 when allocating 4-byte blocks, what could cause this? Well, one possibility is related to memory alignment. On x86 systems, allocations are usually aligned to word boundaries (which for 32-bit would be 4 bytes). But since they're using a 64-bit host system running an i386 emulator, there might be some differences in how the memory is managed. + +Another angle is looking at how malloc works. Malloc doesn't necessarily return memory that's exactly the size requested due to internal overhead and alignment requirements. So even if you ask for 4 bytes, the actual block could be larger because of bookkeeping information added by the allocator. + +Wait a second—the user is using qemu-i386-static, which runs 32-bit code on a 64-bit host. Could there be an issue with how the emulator handles memory allocations? Maybe the malloc implementation in the emulated environment isn't properly handling pointer increments or there's some bug in the way it interacts with the host's memory management. + +Alternatively, perhaps the issue is related to how pointers are being printed. The printf format specifier %x expects a 32-bit integer, but if the pointers are 64-bit on the host, truncating them might cause unexpected behavior. However, since they're running in an i386 environment, pointers should be 32 bits, so that shouldn't be an issue. + +Another thought: could this be related to stack or heap corruption? If the program is freeing the memory correctly but still seeing issues, it's less likely. But if there was some overwriting of memory, it might cause miscalculations in pointer increments. + +But looking back at the problem statement, the user is asking why applying for 4 bytes results in a pointer increase by only 2 bytes. Wait, that doesn't align with their output where each allocation increases by 16 bytes. Perhaps they made a mistake in describing the issue. Or maybe the actual problem is different. + +Wait, perhaps I misread the output. Let's look again: pa is at 0x400051a0, pb at 0x400051b0—difference of 0x10 (16 bytes). Then pc at 0x400051c0 and pd at 0x400051d0. So each allocation is indeed 16 bytes apart, not 2 or 4. So maybe the user's actual issue is different from what they described. + +Alternatively, perhaps in their real scenario, the pointer increments are smaller than expected, but in this example, it's working correctly. Maybe I should focus on the fact that they're using a static emulator and whether there's something wrong with how malloc is implemented within qemu-i386-static. + +I think the key here is to classify the bug into one of the given categories: instruction, syscall, or runtime.
